Powerful DC and AC power supply for a circuit breaker test
Description

POB30ADL is a variable voltage power supply unit ideal for testing circuit breakers, where substation battery is not connected or available. The POB30AD is intended to operate breaker coils, and spring charging motors as a part of commissioning and maintenance testing.
POB30AD generates true DC (ripple free) or AC voltage and can test minimum trip voltage of power circuit breakers. Output voltage is selectable from 1 V to 50 V DC or from 1 V to 40 V AC.
The POB30AD is powerful and versatile unit, with possibility to generate at 230 V mains supply initial current of 30 A as well as continuous current according to the tables below:

The set is equipped with thermal and overcurrent protection. POB30ADL is easy to use and has accessory cable-set with touch-proof contacts.
The POB30ADL has very high ability to cancel electrostatic and electromagnetic interference in HV electric fields. It is achieved by very efficient filtration. The filtration is made utilizing proprietary hardware and software.
Applications
POB30ADL is developed for use in switchyards, electric power and industrial environment. An important part of commissioning and maintenance testing is a circuit breaker testing. POB30ADL is possible to use for:
  • operating circuit breakers
  • supplying spring-charging motors
  • power supply at test with breaker analyzers
  • minimum trip-voltage test of the circuit breaker's coils
POB30ADL have built-in capability to perform an automatic test of minimum trip-voltage. The minimum trip- voltage test is described in a number of international and national standards such as IEC 62271-100, ANSI C37.09 etc. Many other important parameters are possible to test with a breaker analyser. POB30ADL is then used as a power supply unit. It is compatible with breaker analyzers from different vendors. POB30ADL can also be used as a general power supply unit or a temporary battery charger.
Automatic testing of the minimum trip voltage of a breaker

Procedure steps:

1. Make certain that the mains are de-energised on both sides of the breaker, safety   
    grounded and that local safety regulations are followed.
2. Connect Power supply unit POB30ADL to the breaker's coil circuit.
3. Set the minimal test voltage.
4. Set the step voltage.
5. Set the maximal voltage.
6. Press TRIG button.
